Abstract
The determination of traces of beryllium in large samples by the (γ, n) reaction, using a124Sb gamma-source, is in general hampered by the rather high handling costs when a BF3 counter is used for the neutron detection. When manganese dioxide is used as an activation detector, the analysis is possible with a simple facility which can be stored in a water basin. The lower limit of the determination is ∼ 1 μg/g for a sample weight of 50 g.
